Driven largely by ever-rising tobacco prices, he's among a growing number of smokers that have turned to their green thumbs to cultivate tobacco plants to blend their own cigarettes, cigars and chew. Byars normally pays $5 for a five-pack of cigars and $3 for a tin of snuff; the seed cost him $9.

"I want to get to where I don't have to go to the store and buy tobacco, but I'll just be able to supply my own from one year to the next," Byars said.

Although most people still buy from big tobacco, the movement took off in April when the tax on cigarettes went up 62 cents to $1.01 a pack. Large tax increases were also imposed on other tobacco products, and tobacco companies upped prices even more to compensate for lost sales.

Some seed suppliers have reported a tenfold increase in sales as some of the country's 43.3 million smokers look for a cheaper way to get their nicotine fix in a down economy. Cigarettes cost an average of $4.35 a pack, home growers can make that amount for about 30 cents.

It's the latest do-it-yourself movement as others repair their own cars, swap used clothes and cancel yard work services to save money.

"Cigarette smokers say, 'Yeah, we're going to die of cancer, but do we have to die of poverty as well?'" said Jack Basharan, who operates The Tobacco Seed Co. Ltd. in Essex, England. Virtually all of his increased tobacco seed sales have been in the U.S., he said.

However, growing and processing tobacco can challenge even the best gardeners. The nearly microscopic seeds must initially be grown inside and transplanted after the threat of frost has passed.

A seed started in March can be harvested, hung to dry and ready to smoke as soon as October. Some anxious growers have been known to microwave leaves to hasten the drying. For purists, the leaves can be cured, or aged, like a fine wine for up to three years.

"It's actually very labor intensive," said Ed Baker, general manager of Cross Creek Seed Inc. in Raeford, N.C., the No. 1 tobacco seed supplier in the U.S. "There's a reason why cigarette companies make all that money. If it was that easy, everyone would be growing their own tobacco."

Philip Morris USA, the nation's No. 1 cigarette maker, and other big companies are unlikely to shudder. Philip Gorham, a tobacco industry analyst with the investment research firm Morningstar, said he had no data on smokers who switched to homegrown. But he doesn't see it as a mass movement.

"It's one thing to switch from a premium brand to a discount one. It's quite another to switch from buying a manufactured product to roll your own," Gorham said.
